I m'rns Fritz Poppensieker, Cologne. Application May 29; In Germany My invention relates tolathes and more especially to an automatic single spindle turret lathe which is distinguished by an arrangement of parts favouring the disposal of the cuttings. In

such turret lathes the blanks machined in several must frequently be different ways simultaneously, which necessitates a plurality of tools and slides. Hitherto the longitudinal slides formed a hindrance to the discharge of the cuttings particularly when a number of were provided.

longitudinal slides To avoid this drawback according to this invention an open frame is pr cross beam of theframe.

ovided with a tool longitudinal slide and laterally thereof a second longitudinal slide is a position such that supported on the frame in the cuttings formed by the action of the tools of the upper slide cannot collect on it. Preferably the lower longitudinal slide is carried on a bracket-like support which projects from rangement facilitates the mac the bed of the machine. This arhining of the guide surfaces for the lower longitudinal slide.

Two embodiments oi'a turret lathe according to the invention are shown by way of example in the accompanying drawing, in which Fig. l is a perspective front elevation of the lathe,

Fig. 2 being a corresponding rear view, while Fig, 3 is a section along the Fig. 4 illustrates The two standards 0 and d right and left of the with a collecting trough a. for

are erected the'turnings. On e cross beam e, on

which is formed a guideway for the tool slide h, the tools in which operate omthe blank m which is rotated by the spindle Z. slide, but in a plane in front Beneath this upper of the standard is arranged a second longitudinal slide 9 which-is guided on a support I forming a bracket projecting from the machine bed. The clearing between this support f and the right hand standard d for the cuttings to be removed of the machine. The support of the lathe in the form extend to theright hand makes it possible from the front side I which extends in front of a bracket might also standardd and thus unite the ii in Fig. 4. By arranging and d as shown at the two, longitudinal slides h two standards 0 and ii beneath one another and in different longitudinal planes the turnings cut by the tools of the upper slide are prevented-from dropping onto the lower slide.

In the embodiment shown,

the upper slide it 1936, Serial No. 82,565

April s, 1936 (01. as-39) carries the tools in a turret head i, which rotates in a vertical plane. This arrangement affords the advantagethat the tools in this turret head never extend over the lower slide a so that for this reason also turnings are i prevented from 6 dropping onto the lower slide.

Apart from the two longitudinal slides a trans verse slide k may be arranged on the upper beam e in known manner. The spindle I with the blank m to be machined is preferably mounted in the 10 left-hand standard 0.

Thus, according to gitudinal slides are the invention the two lon-' spaced as far from one another; as possible, i. e., they are disposed diagonallyopposite one another with respect to the blank. Simultaneously with this separation of the points at which the tools engage the blank, 9. tool arrangement'whichdoes not mutually interfere is obtained. The upper longitudinal slide cannot possibly be impeded by the cuttings and. 20 the longitudinal slide which is disposedbeneath it and on one side thereof is not affected either and in any'case can readily be cleared of frag- I ments which collect because there is no obstacle near or behind this slide. The wormng of the 2 guide surfaces for the lower longitudinal slide is materially facilitated by the bracket-like er rangement of the guide member f. At the same time this bracket-like portion can serve to receive the means for driving the longitudinal slide. 30
